Hey, definitely don’t judge someone for their car - I drive a beater and actually do this for a living. I am also a cheap person all over and in this business you have to be. One of the best PMs at Point72 drives a Honda Odyssey AFAIK."I drive a Hyundai because I'm really rich, buy my book", etc.
The issue is really the incentives. In most cases, unless you are employed in finance, it makes more sense to sell books and courses than to trade your own capital. Does not mean that everything you hear from these authors/teachers is worthless, but it certainly carries less weight. For what it’s worth, if someone is teaching you “the process” (ie how do you approach alpha research and risk taking), it’s much better than someone teaching you “the method”. Any particular strategy will eventually decay and die (and anyone who says otherwise is full of shit) but the process that you establish to find trades and deploy capital will help you find new alpha.
